No paradox. Grains have some excellent qualities- they store without a
refrigerator, are energy dense (more calories per pound if you're on the
move), high yields, have a short life cycle- so if you move on, you can
start farming them the immediate next season cf fruit trees take years.
Sounds too good to be true- only problem is if you want to live past 45 in
good health.
